  • Abstract
    We present a current status of a Rb/Cs double fountain clock developing at KRISS. Fountain clock has cooling laser beam with (111)-geometry so as to enlarge cooling beam diameter. Currently few 107 Cs atoms are trapped and cooled in MOT. And we observed Ramsey fringes. The linewith of central Ramsey fringe was measured to be 1 Hz with the S/N of 600.
